Figure 1 shows high-brightness LED solder joints after soldering without vacuum. A comparison of the two images makes it plainly apparent that with a vacuum of 10 mbar the number of pores and their surface area has been drastically minimized. In the event of solder joints with large surface areas, as is the case for instance with LEDs, QFNs and Si chips, a smaller number of voids results in improved thermal performance as well as less tilting of the component.
